Product Description

AMERICAN’s 14"-48" Series 2500 ductile iron resilient wedge gate valves are suitable for use in potable water, sewage and fire protection systems. These valves have a rated working pressure of 250 psig with zero leakage. The waterway is clear and unobstructed.

Advantages Over Butterfly Valves

No disc in waterway to restrict flow or to increase pumping costs

Allows passage of pigging devices

Internal parts can be serviced without cutting valve out of pipeline

250 psig rating provides for future pressure increases over the 150 psig pressure rating typically found on most butterfly valves

Benefits

Ductile Iron Construction
The ductile iron body and bonnet provide superior strength and allow a pressure rating of 250 psig. The strength of ductile iron is more double that provided by gray iron. This added strength and higher pressure rating are provided in a compact, lighter design.

250 PSIG Pressure Rating
The Series 2500 is pressure rated at 250 psig to account for typical pressure variations and surges.

UL Listed and FM Approved in Applicable Configurations
Both UL and FM require that we consistently manufacture and test our valves in compliance with their stringent requirements. Our facilities are subject to periodic inspections to assure we are in compliance with their standards.

Certified to NSF/ANSI 61 and NSF/ANSI 372
The Series 2500 gate valve is Certified in all sizes as complying with NSF/ANSI 61 and NSF/ANSI 372, which exhibit compliance with the U.S. Safe Drinking Water Act.

Triple O-Ring Stem Seals
Sealing the lubrication chamber is a series of O-Ring stem seals. The two O-Rings above and one below the stem thrust collar help to isolate the lubrication chamber.

Epoxy Coating Inside and Out
A fusion-bonded epoxy coating is electrostically applied to the interior and exterior of the valve body to help ensure corrosion resistance for a long service life. The coating is applied to all ferrous surfaces after the valve body is shot-blasted clean.

Thrust Washers
Thrust washers are located above and below the stem collar to reduce operating input torque and assist in trouble-free operation of the valve.

Lifting Devices, 14"-66"
All 14"-66" valves are provided with integral lifting devices, which allow the valve to be properly handled without lifting it by the operating nut.

Zero Leakage
Every valve is seat and shell tested after assembly to ensure its rated performance and that the seating mechanism is leak-tight.

Dual Sealing Body to Bonnet Gaskets
The body to bonnet gasket utilizes a unique dual sealing design which incorproates the reliabilty of a flat gasket and an integral pressure energized O-Ring seal.
